Buflovak Vacuum Double Drum Dryer




Manufactured by Hebeler Process Solutions, USA

Vacuum Double Drum Dryers are specified when products require uniform low-temperature drying, non-reactive atmospheric drying or complete solvent isolation and recovery drying.

Utilizing thin film drying via conductive heat transfer under vacuum, these dryers can be designed to meet the most stringent sterile operating environments and are particularly suited for pharmaceuticals, nutraceuticals, vitamin extracts, specialty food items, fine chemicals and solvent reclamation of widely varying densities and viscosities.


Depending upon the application vacuum drum dryers can be designed for batch operation, which requires the chamber to be returned to atmospheric pressure to remove the dried product, or continuous operation, which allows the dried product to be removed from the chamber while under vacuum by utilizing several unique air-lock systems.

Due to the hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a drum dryer’s mechanical design, operating components and ancillary support equipment can be customized to meet each individual process design needs.

Our Vacuum Double Drum Dryers are also installed and used for production of HPAPI – High Potency Active Pharmaceutical Ingredient.

These installations in HPAPI require a specialized containment to ensure that employees and their environment are protected from direct exposure to the pharmaceutical ingredients.
